前言
自發(fā)性遺傳模型為研究癲癇全身性發(fā)作，特別是研究癲癇失神發(fā)作提供了基礎(chǔ)。WAG/Rij大鼠用于研究遺傳性癲癇失神發(fā)作，其行為學(xué)改變、EEG表現(xiàn)（表現(xiàn)為棘慢復(fù)合板波）以及遺傳特性等方面與人類癲癇失神發(fā)作極為相像，已被廣泛用于研究人類癲癇失神發(fā)作。
部分造模方法
使用動(dòng)物：大鼠
【造模機(jī)制】：
WAG/Rij大鼠來源于1924年Bacharach培育的遠(yuǎn)交系Wistar基因突變大鼠。
【模型特點(diǎn)】：
目前常用的失神發(fā)作遺傳模型主要為WAG/Rij大鼠，無論是在清醒或睡眠狀況下，均能記錄到雙側(cè)同步、陣發(fā)性的棘波發(fā)放和兩側(cè)同步對(duì)稱的3Hz棘慢波發(fā)放(spike and wave discharges,SWDs)，同時(shí)伴有臨床失神發(fā)作的表現(xiàn)。
【模型評(píng)估和應(yīng)用】：
能顯著抑制該模型失神發(fā)作的藥物往往對(duì)臨床失神發(fā)作有效，兩者間具有高度相關(guān)性。g－氨基丁酸B1激動(dòng)劑能加重WAG/Rij大鼠模型的SWDs發(fā)放。盡管上述兩種遺傳性失神模型具有自發(fā)失神發(fā)作及SWDs，但因難以大量繁殖，從而使其應(yīng)用受到限制。
